从命令行创建一个新的仓库

touch README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin http://192.168.0.240:3000/useadmin/Null.git
git push -u origin master

从命令行推送已经创建的仓库

git remote add origin http://192.168.0.240:3000/useadmin/Null.git
git push -u origin master

# 远程代码和本地代码合并
git pull --rebase origin master
git push -u origin master

# 强制推送
git push -f

git fetch
git merge
上面两句等价于
git pull

.gitignore 文件如何在 window 上创建？
.gitignore. 文件名两边都有一个点即可创建

如何删除 git add 添加到缓存中文件？

git rm -r -n --cached 文件/文件夹名称  ,预览将要删除的文件

一种是 git rm --cached "文件/文件路径"，不删除物理文件，仅将该文件从缓存中删除；

一种是 git rm --f  "文件/文件路径"，不仅将该文件从缓存中删除，还会将物理文件删除（不会回收到垃圾桶）。

error: RPC failed; HTTP 400 curl 22 The requested URL returned error: 400 Failed reading client body
fatal: The remote end hung up unexpectedly
//设置 post 缓冲区大小
git config --global http.postBuffer 1048576000

合并分支
git fetch origin master
git merge origin/master

递归遍历

git clone --recursive https://github.com/caffe2/caffe2.git

git reset xxx --hard
git reflog
git reset old_xxx--hard

# 更新子模块
git submodule init
git submodule update
